Exposure compensation

Let's recap a few things here.…We've been covering a lot of different modes.…Program mode where the camera automatically picks a shutter speed and aperture…for you, that will give you a good overall level of illumination.…We've also looked at priority modes:…shutter priority where you get to pick a shutter speed and the camera picks a…corresponding aperture that will yield a good level of overall illumination;…aperture priority mode where you get do pick an aperture, and the camera picks…a corresponding shutter speed that will yield a good level of overall illumination.…Are you sensing a pattern here?…I keep saying that one phrase over and over over: "a good level of illumination."…With all of the controls we've been looking at so far, the camera will always…try to get you the same level of brightness.…

I'm going to switch to aperture priority mode here real quick.…I am metering, and I have dialed in an aperture of f11.…If I change that aperture--I'm going to go down to f 5.6 here--…as I change that, the overall brightness in the scene has not changed.…

Arriving at the best exposure for a photo is part science and part art. In Foundations of Photography: Exposure, Ben Long helps photographers expand their artistic options by giving them a deep understanding of shutter speed, aperture, ISO, and all other critical exposure practices. This course covers the basic exposure controls provided by all digital SLR cameras, as well as most advanced point-and-shoot models. Learn how to master a camera's metering modes, how to use exposure compensation and bracketing, and much more. By the end of the course, you'll know how to develop an "exposure strategy" that will allow you to effectively employ your exposure knowledge in any shooting situation.
